'loa/E'womitl may concern.: y Be it known that I, Hnnnrv lWonrr, a citizen of the United States, and a resident of St. Paul, in the county of amsey and State of Minnesota, have invented new and useful Improvements Methods for lllalring iher Shingles, of which 'the following is a specification.

One object of my invention is to provide in a machine for in.; l D liber shingles, means for holding matenal firmly :and performing e series of operations on the ma terial while it is in the holding means.

Another object of my invention is to pro-l embodied in the Inoving table tools arranged to perform nnctions on the shingle materiel in a certain predetermined cycle.

Another object of my invention is to provide means for stripping granular and witter proof coats from the shingle material While it is in motion. v

Another object of my invention is to pro vide ineens for slitting and securing the shingle material While it is in motion.

Another object of invention is to provide an improved method't'or making fiber shingles wherein the "material is carried along together with certain tool holders and kthe operations performed on the material While it is in motion.

.Another object of my invention is to provide Ineens for forming the side edges of the shingle tabs While the shingle material is in motion. f

With these and incidental objects in view, the invention consists of certain novel features of construction and combinations of arts, the essential elements of which are hereinafter described with reference to the drawings which accompany and form a part of this specication.

Figure 1 is a side elevation of my machine for manufacturing ber shingles.

Fig. 10 and Fig. 11 are side elevations of the raising and lowering cams.

Fig. 13 is a plan View of the machine as shown in Fig. 1. but with the upper half thereof removed along the line lil-1?. Fig-14 is a plan view of the upper half of the machine when turned upside down. l

his machine is designed to receive a sheet of suitable stock at 17, Fig. l, and to perform. certain operations on thesheet as 1t asses through the machine "from left to rig t so that When it lesvesthe machine :1t 17 shingle strips, such as shown in Fig. 2, will have been completed.

A frame l, Figs. l, 13 and 14, has mounted thereon slidnble bearings 2 and fixed hearings 3, Fig.. l.

Journaled in hearings 2 and 3 are shafts et which have mounted thereon sprockets 5, carrying the endless sectional tables 6 and fi.

he outer ends of the shafts 4`, shown :it the left of Fig. 1, have mounted thereon gears 4 which mesh with gears 9 and 10, as shown.

The gear 10 is carried by a. shaft ll which has mounted on its opposite end the pulley 12, which is to he drivfen by the source of power operating the machine.

The endless tables 6 and 7 are composed of similar units 16 hinged together'at 40 by pins 4-1, Figs. l, 8 and 9, so as to form endless belts or moving tables which, during their horizontal motion, present flat-fand rigid table-like surfaces. Y

Itis apparent that the rotation of the p 1.2 will drive the moving tables and the `direction of rotation is such that along the line 17-17vthe tables move from lett to right and will carry betweenthem'material introduced at 17.

The units 16 are preferably made Witi. .a

WJiii the sempiiig knife 25 and i; ing knife in position with regard to the materia?. passing through the machine, as shown in Figs. 3 and li, the cams 5@ and 51, i2, 'i3 and 14E are thmsting the shaft 2i oet-h in the iowei' and upper units tasverseiy so that the scraping kziife scrapes he meteiai from the top surface of the sheet of maeri'al.

At this point Vee-sier wheels of the two siies impingze on the pins 49 and the shefs are roe'ed 20 degrees eaclu ,ne units 'pass aiongf through the machine wiiiout furthe? function unti the points 64 emi 65 are reached, and it Wiii be seen that the upper shaft 2l is new turned so that 'no ioni een piesened to the material, Whiie the iowei shaft is Se aimed that the forming tonivi, is pieseued to the materiel.-

After the upper shaft 2l has been returned to its normal position at the point TO and While the lower shaft is still in operative position With respect to the aper, the shafts are moved transversely by tiie camming surfaces 72 and 73, this motion performing no function 011 the upper shaft and likewise no function on the lower shaft except in the case of every fifth loiver shaft, which carries the two cutting oit knives 43, and'in the case of these shafts the cutting olf knives are drawn across the material, thus completely severing it.

As there are tvvo knives 43, it is evident that it is only necessary for each knife to be drawn one-halt' the length oftlie line 24,

Fir?. 2, to completely sever the. shingle strip.
